Same as OEM
Works very well-same quality as OEM but far less expensive! Cleared my check engine light and codes for my 2013 Chevy Cruz.

Correct part wrong listing for a Trax
Now, per the info on Amazon, this is not to fit my 2017 Trax lt. I added a pic to show that the old mag on top is the same number as the bottom new one I just received. I would hope people who do the data entry will fix this, but I’m not gonna hold my breath one it. The part is working fine and no more missing. Will update this part in a few months

Only lasted 1.5 years
For $100 and it only to last a year and a half, not too bad but definitely a little disappointing. Fit perfectly for my Chevy Cruz 2012.

Fixed the AIT problem on my 13 sonic 1.4
I had 3 codes low voltage to AIT I had originally bought the sensor that is on the intake after the intercooler but it was the 8 pin on the air cleaner easy fix and all 8 pins detect something to the obc so some may work when others don't fixed the problem .

Works Perfectly!
I bought a cheaper brand to save money and regret it as it did not allow my car to run correctly. So I spent the money to buy this product and it was absolutely worth it. This is a quality and reputable brand.
